Lower drive wheels to floor and remove blocking. Drive and Steer Wheel Mounting 1. Inspect   and   tighten   drive   wheel    lug    nuts    to torque spec:  470-530 Ib-ft (637-719 N•m). 2.    Inspect   and   tighten   steer   wheel   lug   nuts   to torque spec:  265-338 Ib-ft (360-458 N•m). Counterweight Mounting 1.    Check   and   tighten   both   inside   and   outside counterweight   mounting   bolts   to   torque   spec: 240-265 Ib-ft (325-360 Nom). 2.    Check and tighten all overhead guard mounting bolts to torque spec: 50-55 Ib-ft (68-75 N-m). 3.    Inspect  and  tighten  the  driver's  seat  mounting bolts.  Torque spec: 15-22 Ib-ft (20-30 N-m).
